fJildu = flullldl vl for E L ()
in each of the following cases:
a) There exists a lifting p of L (v) such that plU] = U.
B) E is separable and there exists a countable norming subset
SC Z.
v) E is separable and the function t UI(t)x is v-measurable for
every x E E.
6) The function U is v-measurable (in this case we do not need
the direct sum property on v).
